Should I start thinking about moving away from embedded software development?

Hi, i have been an embedded software developer for about 5 years now, and i had a constant feeling that my skillset has plateaued over the last 18 months, i feel like I'm not learning anything new. My job is a constant cycle of a)get some data sheet b)do some research c)write a driver.

I've gotten to the point where i don't think i can read anymore books about coding in C, i love the language and the thrill of playing around hardware, but I'm honestly not sure how i can further my career while maintaining technical roles instead of moving into management/architect type roles.

Would love some insight from fellow embedded devs.
